This invention relates to certain newand useful improvements in snowplows and the primary object of the present invention is to provide asnow plow that maybe mounted on a. vehicle, such as a locomotive' or thelike, for clearing the trackway of snow accumulation and may be alsoused on any other type of vehicle as may be found desirable for clearingthe snow'from side walks,-boulevards, highwaysand the like. 1 V

A still further object'of the invention is to provide a snow plow of theabove mentioned character which will insure'depositing of the plowedsnow to either side of the 7 road -;or walk being cleaned,

A still further object of the invention is'to provide a plow of the'above mentioned character, which is comparatively simpleinconstruction, consists of relatively few parts,'can be readily mountedon a locomotiveor other vehicle without requiring a materialjaltera tionin the vehicle, and which will otherwise be found practical,-andthoroughly efficient for 'the'purpose designed. Y

' Other objects andjadvantages of the invention will becomeapparent-during a study of the following description, taken inconnection with the accompanying drawings wherein: Figurel is a verticalsectional view taken through the plow, certain part -bein shown inelevation. j i

Figure 2 is a horizontal sectional view taken through the plow,

Figure 3 is a vertical-transverse sectional view taken through theplow.-

Figure 4 is an elevationalview-of one of thecutters; 3 1 v "Referringmore in detailto the drawings,

it will be seen that the plow includes a frame structure comprising fourhorizontally disposed angle irons 1 arranged in rectangular formationand disposed one adjacent each corner of a; casing, the latter beingsubstantially U-shaped in crosssection and including a bottom'wall-fzand oppositely disposed side .walls3.- i c Q Rising from; the bottomwall;- 2 between walls 3 adjacent the rear end ofthe casing inwardlyfromsaid endis, arear wall 4 1the upper end of which projects beyond theopen top of the casing. A brace or reinforcing member 5 engages theupper end of the wall 4 and extends transversely of the casingfrom Vone'side wall to the otherof the casing; The brace or'reinforcing member5 is confined *between wall and a transverse angle-bar 6 that connectsthe upper pairs'of angle irons 1.)

a An annular fan'housing 7 is'arrange'd in the casing forwardly of wall4 and at the top to thereof isprovided with a pair of openings 8, 9,from which extend upwardly and outwardly therefrom and in oppositedirection, nozzles or conduits 10,11 which at their free ends openlaterally of the plow.-

" The conduits 10, 11, maybe formed in any suitablemannef and aresecured to wall 4 as at 12, 13; Rising from the bottom walls2 of thecasing is apair of spacedparallel partition walls 14, 14, that arearranged forwardly 7 of the fan housin 7 and at right angles thereto.The partition walls 14, 14 divide the easing into a pair of compartments15-15 that open outwardly at the forward end of the plow. The partitionwalls 14'14 formtherebetweena gear chamber 16 closed'at. each end byvertical wall members-17 17,

'and the chamber is adapted to containa suitable lubricant.

The forward end wall of fan housing 7,7is' provided with an opening 18which connects the fan housing with the compartments Extendinglongitudinally through the easing is a driven shaft 19. Theshaft 19ex'-tends through suitable openings "provided thereforin wall 4 and anadjacent end wall of the fan housing; the shaft passing through Suitablebearings 20, 21=are provided for the shaft 19 in the walls 1717. f'Mounted on shaft 19 for rotation therewith and located within thefanhousing 7 is a blower fan 22, the blades of whichare relativelyarranged as to have adjacent blades 5 project radially from the hub ofthe fan at substantially right angles to one another and alternateblades projecting'radially from the hub in opposite direction. (See=Figure'3.)

Arranged'within each compartment 15 and adjacent the forward end thereofis a pair of 7' i 14 and arranged withinthe gear chamber for of shaft19.. At its free end-shaft 19 is adaptmesh with a worm 31 on an adjacentportion ed to be coupledas at 32 to one end ofa motor shaft, a portionof which isindicated Thus as: is apparent-,when power is trans.-mi'tted; to-shaft 19, fan' 22 willbe rotated andlmovement of shaft 19 istransmitted to shafts 24 and 25 through the gearing dei scribed d t 'l,thus rotating th tt 23 simultaneously with fan 22. 1 The "packedsno'wandj ice willbe -out and loosed by contact of the cutters withthefsame, the par- 7 ticlesof snow and ice being subsequently drawninwthe casing by the f-suction created by thev fan 22, the particles ofsnow and' ice in the casing being drawn into the fan. housing 7. Thesnow and iceparticlesthusdrawn into fan housing 7 areiferced' into theoutlet conduits 10,111Lto be depositecl'orr o it c-sideslof the plo aFor closing the top of the casing forwardly of the fan housing 7 thereis provideda removable cover plate 34 held in position-by cross bars35-bol'ted at their ends to adjacent angleirons 1. V At its f forwardend the cover plate 34 projects forwardly of the correspondng end of thecasing, Y i f .-'E Xtending acrossthebottom of the casing at the forwardend thereof is abladef36 that has a convex cutting edge as suggested inFigureZ; a i} 7 Openings 8. 9 are; controlled by sliding valve plates37, 38 that are arcuate in cross section and are'adaptedfor slidingmovement through suitable slots providedin the wa1l'4 V and bracemembers V Each of the cutters- 23 comprises a: pair of spaced 'hubs39,40 respectively provided. with spokes 4 1.radiatingtherefroni',,thespokes of hub 40 being arranged in alternate relationwith respect to the spokes-ofhub39 and in advance of the spokes on hub39. Blades 42 supported by pairs, ofspokes 41 are thus inclinedobliquely with respect to'the axes of the respective shafts 24,?25ytoinsure guiding of the snowparticles rearwardly and into thecasinggand' toward oppositesides of the plow.

Extending transversely of thecasing' at the bottom thereof, and arrangedin each: compartment' 15 is a member 43,;located adjacent directing-thesnow into, the jfan housing.

From the foregoing then it will be seen that we have provideda snow plowthat may be readily mounted "on any desired type of vehicle and which'willbe found in actual practice to be thoroughly eflicient forclearing, a path through snow accumulation.

Even though'we have herein shown and described the preferredwembodimen'tof the inventionit is to -be understood that the same is susceptible ofimprovements, modifications and changes coming within the scope of theappended claims.

. pHaving thus described our invention, what .we claim,- as new is: Y
